The forgiving boyfriend.

TBDL.

Basically:

He's understanding, even though he's hurt. He forgives you, though he clearly states he'll expect the same treatment if he ever falters too.

In this path, they undergo counselling, and end up on a cruise making up to each other. They also realize they need more experience, and as they try out new things, they both grow above and beyond every sexual level they could have imagined. I'm too lazy to write this one this week, though.
